Relative expression levels of lncINS-IGF2 in lung cancer tissues and cell lines. A, lncINS-IGF2 expression was assessed following microarray analysis of lung cancer tumor specimens (n = 3) and normal adjacent lung tissue (n = 3). B, The expression of lncINS-IGF2 was measured by qRT-PCR in A549, H1299, and H441 lung cancer cell lines, HBE cells, 293T cells, and HeLa cells. *P < .05 versus normal group. Results are expressed as the mean (SD) of the samples and each analysis was performed in triplicate. qRT-PCR indicates real-time quantitative polymerase chain reaction; SD, standard deviation.
